The assembly department obtains fish and then processes them into frozen fillets and then prepares the frozen fish fillets for distribution to its retail sales department. Direct materials are added at the initiation of the cycle. Conversion costs are incurred evenly throughout the production cycle. Before inspection, some fillets are spoiled due to undetectable defects. Spoiled fillets generally constitute 4% of the good fillets.

(b) Prepare a production cost worksheet using weighted average for the assembly department? ( showing the total costs to account for, cost per equivalent units, and assign costs to units completed and transferred out, to abnormal spoilage and to units in the ending work-in process.) (c) Find the cost per unit completed and transferred out
